Discussion. The discovery of male specimens of U. alboclypeata stat. nov. shows that the general appearance of these males is similar to that of Ingrisch’s species described later. Males of these taxa slightly differ from each other by characteristic ornament on anterior part of head and on pronotum (see key to species and subspecies of Ultragryllacris ), but the process of male 9 th abdominal tergite looks similar (elongately triangular in dorsal view) in the both taxa; however, the apical part of this process in U. triangula is slightly more bent downward than in U. alboclypeata . Female subgenital plate in U. alboclypeata lacks median furrow and has apical part shallowly concave, but in U. triangula , this plate is with faint median furrow and almost rounded apical part (compare Figs. 72 and 73 ). Thus, on the base of these characters, we assume that U. triangula should be considered only a subspecies of U. alboclypeata .

FIGURES 64–80. Apex of female abdomen: Ultragryllacris alboclypeata alboclypeata (64, 72); Ultragryllacris a. triangula (65, 73); Ultragryllacris pulchra (66, 74); Ultragryllacris nan (67, 75); Ultragryllacris rubricapitis from Mengla’s population (68, 76) and Simao’s population (77); Ultragryllacris intermediata sp. nov.

Note for subgenital plate: small dots near greyish area (75, 79, 80) denote membranous area; greyish area of all subgenital plate denote sclerotized band excepted basal part of this plate (73) is not pictured (no clue about sclerotized band from Ingrisch, 2018).
